Tokenlock 3.5 has been released tot he app store after almost 5 months. Wow. Wonder if that was worth it!
TokenLock - Lock your Mac when you walk away.
Tokenlock helps you improve the security of your Mac by locking it when you:
Remove a USB device you have designated from your Mac.
Move a bluetooth device out of bluetooth range of your Mac.
Tokenlock
was designed to increase the security of your Mac by automatically
turning on the screen saver, or locking your system whenever a USB
device or a Bluetooth device are removed from your system.
You
can tell it to monitor almost any USB device, such as a hard token like
YubiKey, a removable flash drive or any other USB device for that
matter. Whenever the device is disconnected it will immediately lock
your Mac.
Tokenlock can monitor any Bluetooth device to check
if it is removed from range, such as your cellphone, headset or other
Bluetooth device. Token lock checks periodically based on a schedule you
choose to see if the Bluetooth device can still be seen. You can set
diffent schedules based on whether or not your Mac is plugged into power
or is simply on battery to conserve battery power.
Tokenlock checks
for the device instead of having to have the device paired with your
Mac, since not all devices can "connect" using Bluetooth but may still
be seen in the Bluetooth device list.
In addition, you can easily lock your Mac manually using the TokenLock menu.
Tokenlock can be set to required a password to change settings or to quit the app, further securing your system.
Features:
MultiThreading: Checks are done in the background, so that TokenLock remains responsive.
Sleep
Aware: When the computer sleeps, this causes USB disconnections.
TokenLock is smart enough to realize this and avoids “Double locking”
your Mac when the USB device you choose has not re-initialized yet after
sleep mode.
Note: TokenLock only locks your Mac. Having it
auto-unlock a Mac would be a security risk since anyone could use a
similar device to bypass your security.
